Yes, completely free. No accounts, no subscriptions, no ads. Open source and community-driven.
Yes. Crunchy-Sync only synchronizes playback — it does not stream or share any video content. Each participant watches through their own Crunchyroll account.
Absolutely! Each user selects their own audio and subtitle preferences on Crunchyroll. Crunchy-Sync only synchronizes the playback position (play, pause, seek) — the language track is independent.
There is no hard limit. Rooms have been tested with up to 10 people, but technically more should work. Performance depends on your internet connection.
All participants are automatically redirected to the new episode. The video pauses for everyone, and each user can press the Ready button. Once all participants are ready, playback starts automatically.
Room data and chat messages exist only in server memory (RAM) and are deleted when the room closes. The website counts page views for simple statistics, without cookies and without storing IP addresses or room codes. Read our Privacy Policy for details.
No. Crunchy-Sync is an unofficial community project. It is not affiliated with, endorsed by, or associated with Crunchyroll or Sony Pictures Entertainment.
